The old name for this very common Ophiuroid is Taeniaster beneckei. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 135: "The mouth-angle plates are slender and abut to form a characteristic V-shape. The disc is constructed of oval-shaped scale-like plates held together by a reticulated pattern of granular skin. The interradial margin is concave or rounded and lacks marginal plates. The proximal ambulacral furrow is broad. The five arms taper evenly into long whip-like tips. A finely granular skin covers the dorsal surface of the arms. The ambulacrals are alternating, unfused and boot-shaped. The foot is only slightly longer than the top of the boot. The laterals are crescent shaped and ear-like. They bear up to five groove spines and five evenly tapering vertical spines, the oral-most one is the longest. The vertical spines decrease in length distally along the arms. Identified by oilshale.
